This page presents video examples on x86 platform using OpenWebRTC.

H264

Unidirectional Elements

Example

In this example we use rrwebrtcbin to send a video stream and rrwebrtcbin to receive the video stream.

Send Pipeline

The following pipeline will send a color bars h264 video stream:

gst-launch-1.0 rrwebrtcbin start-call=true signaler=GstOwrSignaler \
signaler::server_url=https://webrtc.ridgerun.com:8443 \
signaler::session_id=1234ridgerun name=web videotestsrc is-live=true ! queue ! videoconvert ! \
x264enc key-int-max=2 ! rtph264pay ! queue ! web.video_sink

Receive Pipeline

The following pipeline will receive the video stream and display it:

gst-launch-1.0 rrwebrtcbin start-call=false signaler=GstOwrSignaler \
signaler::server_url=https://webrtc.ridgerun.com:8443 \
signaler::session_id=1234ridgerun name=web web.video_src ! rtph264depay ! avdec_h264 ! videoconvert \
! ximagesink async=true

You should be able to see a video pattern similar to Fig.1.

Bidirectional Element

Example

In this example we use two rrwebrtcbin elements, each sends a video stream and receives each other video stream.

Send-Receive Pipeline

The following pipeline starts the call:

gst-launch-1.0 rrwebrtcbin start-call=true signaler=GstOwrSignaler \
signaler::server_url=https://webrtc.ridgerun.com:8443 \
signaler::session_id=1234ridgerun name=web videotestsrc is-live=true ! queue ! videoconvert ! \
x264enc key-int-max=2 ! rtph264pay ! queue ! web.video_sink web.video_src \
! rtph264depay ! avdec_h264 ! videoconvert ! ximagesink async=true

Send-Receive Pipeline

The following pipeline joins the call:

gst-launch-1.0 rrwebrtcbin start-call=false signaler=GstOwrSignaler \
signaler::server_url=https://webrtc.ridgerun.com:8443 \
signaler::session_id=1234ridgerun name=web videotestsrc is-live=true ! queue ! videoconvert ! \
x264enc key-int-max=2 ! rtph264pay ! queue ! web.video_sink web.video_src \
! rtph264depay ! avdec_h264 ! videoconvert ! ximagesink async=true

You should be able to see two windows with a video pattern similar to Fig.1.

VP8

Unidirectional Elements

Example

In this example we use rrwebrtcbin to send a video stream and rrwebrtcbin to receive the video stream.

Send Pipeline

The following pipeline will send a color bars vp8 video stream:

gst-launch-1.0 rrwebrtcbin start-call=true signaler=GstOwrSignaler \
signaler::server_url=https://webrtc.ridgerun.com:8443 \
signaler::session_id=1234ridgerun name=web videotestsrc is-live=true ! queue ! videoconvert ! \
vp8enc ! rtpvp8pay ! queue ! web.video_sink

Receive Pipeline

The following pipeline will receive the video stream and display it:

gst-launch-1.0 rrwebrtcbin start-call=false signaler=GstOwrSignaler \
signaler::server_url=https://webrtc.ridgerun.com:8443 \
signaler::session_id=1234ridgerun name=web web.video_src ! rtpvp8depay ! vp8dec ! videoconvert ! \
ximagesink async=true

You should be able to see a video pattern similar to Fig.1.

Bidirectional Element

Example

In this example we use two rrwebrtcbin elements, each sends a video stream and receives each other video stream.

Send-Receive Pipeline

The following pipeline starts the call:

gst-launch-1.0 rrwebrtcbin start-call=true signaler=GstOwrSignaler \
signaler::server_url=https://webrtc.ridgerun.com:8443 \

vp8enc ! rtpvp8pay ! queue ! web.video_sink web.video_src ! rtpvp8depay ! \
vp8dec ! videoconvert ! ximagesink async=true

Send-Receive Pipeline

The following pipeline joins the call:

gst-launch-1.0 rrwebrtcbin start-call=false signaler=GstOwrSignaler \
signaler::server_url=https://webrtc.ridgerun.com:8443 \
signaler::session_id=1234ridgerun name=web videotestsrc is-live=true ! queue ! videoconvert ! \
vp8enc ! rtpvp8pay ! queue ! web.video_sink web.video_src ! rtpvp8depay \
! vp8dec ! videoconvert ! ximagesink async=true
